This page documents and provides access to various data sets
available at UT-Dallas. They are primarily intended for use by students taking GIS
classes but are made available on the web as a courtesy. Certain files are
copyrighted. Many files are large! For a general guide to data sources on the
Internet go to:

Census tract boundary files for the Dallas Fort
Worth area from 1940 through2000.The 1940 through 1980 files
include associated
attribute data from the US Census of Population. Files are zipped by decade and contain a README file with additional
information.

Files listed here are available via drive mappings [ GISData on
'Charlotte' ] in the Green
Microcomputer labs in GR 3.206 and GR 3.602. Other users on the UT-Dallas
campus network may also access these files with appropriate drive mappings.
They are also accessible via the web at
http://epps.utdallas.edu/mgis/gisdata/
However, they have not been optimized for web access. For example, multiple
files may need to be downloaded for useable results and files in ESRI coverage
format cannot be downloaded in a readable form.
